<a name="GstDiscoverer.description"></a><h2>Description</h2>
<p>The <a class="link" href="GstDiscoverer.html" title="GstDiscoverer"><span class="type">GstDiscoverer</span></a> is a utility object which allows to get as much
information as possible from one or many URIs.</p>
<p>It provides two APIs, allowing usage in blocking or non-blocking mode.</p>
<p>The blocking mode just requires calling <a class="link" href="GstDiscoverer.html#gst-discoverer-discover-uri" title="gst_discoverer_discover_uri ()"><code class="function">gst_discoverer_discover_uri()</code></a>
with the URI one wishes to discover.</p>
<p>The non-blocking mode requires a running <a href="/usr/share/gtk-doc/html/glib/glib-The-Main-Event-Loop.html#GMainLoop"><span class="type">GMainLoop</span></a> iterating a
<a href="/usr/share/gtk-doc/html/glib/glib-The-Main-Event-Loop.html#GMainContext"><span class="type">GMainContext</span></a>, where one connects to the various signals, appends the
URIs to be processed (through <a class="link" href="GstDiscoverer.html#gst-discoverer-discover-uri-async" title="gst_discoverer_discover_uri_async ()"><code class="function">gst_discoverer_discover_uri_async()</code></a>) and then
asks for the discovery to begin (through <a class="link" href="GstDiscoverer.html#gst-discoverer-start" title="gst_discoverer_start ()"><code class="function">gst_discoverer_start()</code></a>).
By default this will use the GLib default main context unless you have
set a custom context using <a href="/usr/share/gtk-doc/html/glib/glib-The-Main-Event-Loop.html#g-main-context-push-thread-default"><code class="function">g_main_context_push_thread_default()</code></a>.</p>
<p>All the information is returned in a <a class="link" href="GstDiscoverer.html#GstDiscovererInfo"><span class="type">GstDiscovererInfo</span></a> structure.</p>

<p>This signal is emitted after the source element has been created for, so
the URI being discovered, so it can be configured by setting additional
properties (e.g. set a proxy server for an http source, or set the device
and read speed for an audio cd source).</p>
<p>This signal is usually emitted from the context of a GStreamer streaming
thread.</p>
